,VALVE M ECHAN'ISM.

SPECIFICATION forming part of Letters Patent No. 280,011, dated June 26,1883.

Application filed January 23, 1883.

To a/ZZ whom tm/ay concern:

` Be it known that I, JOHN W. BRADLEY, of Stratford, in the county ofFairfield and State Connecticut, have invented a certain new and usefulImprovement in Valve Mechanism, of which the following is aspeciiication, reference being had tothe accompanying drawings.

anism, showing the bottom part in elevation,`

and Fig. 2 is also a similar central section of the shell, but shows asection of the valveplug, taken at right angles with the section shownin Fig. l, and within the plug is exhibited the hinge-valve in plan.

Referring to the letters upon the drawings,

A indicates a shell provided with a central transverse opening, B, forrecelving a stop cock plug, and having upon either end a screwthread orother suitable or ordinary means for making pipe-connections. t

C indicates a stop-cock plug provided with transverse openings D forpermitting the passage of steam, water, or other fluids in the usualway. This plug is fitted andsecured in place, and provided with meansfor turning it in any ordinary or usual way, so that it may present itstransverse openings D in line with the pipe-openings inthe shell, or beturned to present its side to the pipe-openings, and thus permit orprevent the passage o'f gas or liquid. As described thus far, the devicepresents no (No model.)

form of valve may be employed within the.

hollow plug. Thus it will be seen I provide a combined stop-cock andcheck-valve in one; and it will further be observed that my checkvalveis capable of operating in either direction, because when turned so asto be opposite and adjacent to one pipe-connection it will permit a flowin one direction, and when turned half around, so as to be opposite andadjacent' to the other pipe-connection, it will permit a flow in theother direction. Thus I am enabled to transfer iiuids from onereceptacle to another and back again withoutproviding separate andindependent means for the two purposes, which is a great economy.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is .l

The combination of a shell with openings through it on the same plane,and the hollow stop-cock plug 'with openings through it on the sameplane with the openings in the shell, and provided with a check-valve,substantially as set forth, whereby iiuid may be passed in eitherdirection, substantially as set iorth.

In testimony whereof I have hereunto subscribed my name this 19th day ofJanuary, A. D. 1883.

JOHN IV. BRADLEY.
